1. "Fossil fuels" are nonrenewable resources that are considered essential for the operation of many factories and industries. Burning them accounts for most of the carbon emissions on Earth, and this leads to "global warming."

2. "Forests" are considered "carbon sinks" because they have a role of absorbing the carbon dioxide in the atmosphere. Cutting down the trees (deforestation) makes forests barren. It then leads to more carbon dioxide in the air.

3. Waste disposals in landfills contribute to the amount of methane that is released into the atmosphere. Methane is considered a potent greenhouse gas that affects people's health.

Many foods, for example, bacon and salt cod, are preserved with high concentrations of salt applied to the outside of the meat.

Rama09 [41]

High concentrations of salt can inhibit the growth of bacteria by causing the bacteria to shrink because water leaves the bacterial cell.

<h3>What is a Hypertonic solution?</h3>

This is defined as a type of solution which has a large amount of particles which are dissolved thereby making it have a high concentration.

High concentrations of salt applied to the outside of the meat means it is hypertonic and therefore causes the bacteria to shrink because water molecule leaves the cells thereby destroying their structure preventing metabolic reactions from occurring which leads to their death.
